Redmine

I recently noticed some little quirks when creating wiki pages with certain special characters.
For instance, I can write on a wiki page a link to a new page as [[M&P]]. As soon as I click on submit, the link to this page is shown in the wiki as M& (without the letter P). However, the resulting wiki page is called M&#38P.
The next problem is when I write a link as [[M#P]] on a wiki page and click on submit. This link is shown as M, the resulting wiki page gets the name M#P, which may dangerous because a hash # has a special meaning in URLs.
Let's look at a link [[M%P]]. The resulting link to this wiki page is correctly shown as M%P. But the wiki page itself is named M%25P.
